Non-aligned u32 read in Chacha20 encryption and decryption

The implementation does not enforce alignment requirements on input slices while incorrectly assuming 4-byte alignment through an unsafe call to std::slice::fromrawpartsmut, which breaks the contract and introduces undefined behavior. This affects Chacha20 encryption and decryption in crypto2...
